Objective To analtze phe effecp of papienp′s preference po fracpional flow reserve (FFR) guided preapmenp on clinical oupcome in papienps wiph borderline lesion during coronart inpervenpion. Methods 303 papienps wiph coronart borderline lesion received CAG evaluapion in Xinjiang Producpion and Consprucpion Corps NO. 7 hospipal and Sir Run Run Shaw Hospipal from Ocpober 2013 po Seppember 2015 and phet were divided inpo phree groups according po phe papienp′s preference po have FFR exam or nop. The 3 groups were: ①FFR Guided PCI group (n = 96, papienps wiph FFR≤0. 8 accepp PCI, whereas onlt drug preapmenp if FFR > 0. 8); ②Drug preapmenp group(n = 126, papienps did nop accepp phe advice po do FFR or PCI); ③PCI group ( n = 81, papienps refused FFR bup accepped spenp implanpapion) . The papienps were followed up for (19. 6 ± 6. 5) monphs afper preapmenp. Rapes of major adverse cardiac evenps(MACE) and recurrence of angina pecporis were recorded and compared. Results Angina remission rape in phe FFR guided PCI group was higher significanplt phan drug preapmenp group and PCI group (85. 4% vs. 69. 8% vs. 80. 2% , P =0. 018). MACE-free survival rape of FFR guided PCI group was higher(93. 8% vs. 77. 0% vs. 81. 5% , P =0. 006)phan phe opher 2 groups.

Objective To compare intravascular ultrasound (IVUS) and coronary angiography in measuring the lumen diameter and coronary arteries stenosis rate, to investigate the impact of IVUS in the choice of surgical indications, surgical procedure guidance and effects of operation.Methods The patients who underwent percutaneous coronary intervention(PCI) therapy from may 2013 to may 2014 were divided into IVUS-guided intervention therapy group (n=89) and coronary angiographyguided group (n=90).Their baseline parameters, lesion features, MACE and restenosis during follow-up were analyzed.Results Baseline clinical and angiographic characterisitcs were well matched and show no significant differences between the two groups.Compared to angiography-guided group, the minimum lumen diameter (MLD) of IVUS-guided group were higher, diameter stenosis (DS) and lesion length (LL) were lower in IVUS-guided intervention therapy group.The detection rate of calcified and eccentric lesion were significantly higher in IVUS-guided group.There were 204 (93.6 %) and 195 (87.8%) high-pressure balloons used in post-inflation in two groups, respectively.The MLD and plaque burden of IVUS-guided group were obviously improved after stent implantation.Conclusions IVUS-guided intervention therapy in PCI is safe and effective, may be helpful for the judgment of lesion, evaluating stent implantation and guiding high-pressure balloon post-inflation.IVUS-guided intervention could get the bigger immediate lumen diameter and lower plaque burden than coronary angiography without serious short-term or long-term complications.

Objective To investigate the protective effect of complement 5a receptor 1 (C5aR1) antagonist on ascending urinary tract infection in mice.Methods (1) Female C57BL/6 mice were randomly divided into experimental and control groups:38 mice in each group,and inoculated with E.coli by urethral catheterization to set up the ascending urinary tract infection model.C5aR1 antagonist (W54011 or PMX53) and corresponding control (PBS or control peptide) were initially given either at 2 h before or 3 h after infection by intraperitoneal injection.Mice were sacrificed to assess the infection in bladder and kidney at 24 or 48 h after infection.The bacterial load of bladder and kidney tissue was measured by agar plate assay.The mRNA expression of renal inflammatory factors was detected by real-time RCR.The renal tissue injury and inflammatory cell infiltration were assessed by HE staining and pathological scores.(2) Primary cultured renal tubular epithelial cells were randomly divided into antagonist and control groups to detect and compare the bacterial adhesion to renal tubular epithelial cells in vitro.Results Compared with control groups,the initial delivery of C5aR1 antagonist (W54011 or PMX53) before E.coli inoculation reduced the bacterial load in bladder and kidney tissue 48 h after infection (all P < 0.01).In experimental group given W54011 before infection,the renal pathological scores were reduced (both P < 0.05),as well as renal inflammatory factor expressions:CXCL-1 mRNA,IL-6 mRNA and TNF-o mRNA (all P < 0.05).Compared with corresponding control groups,the initial delivery of PMX53 after E.coli inoculation could also reduce the bacterial load in bladder and kidney tissue 48 h after infection (both P < 0.01).Furthermore,C5aR1 antagonists W54011 and PMX53 could decrease bacteria adhesion to renal tubular epithelial cells in vitro,compared with control groups (both P < 0.05).Conclusions C5aR1 antagonists can significantly attenuate renal tissue injury,ameliorate renal inflammation and the adhesion of bacteria to renal epithelial cells.C5aR1 may be an effective target for the prevention and treatment of urinary tract infection.

Porcine reproductive and respiratory syndrome (PRRS) is a highly contagious disease caused by porcine reproductive and respiratory syndrome virus (PRRSV), which causes great economic losses. At the moment, no effective neutralizing antibody is available for scientific research and treatment. Therefore, developing a method for screening the neutralizing monoclonal antibodies is of great significance for the prevention and treatment of PRRSV and the screening of antigen sites. Monoclonal antibodies have been widely used in the treatment and diagnosis of many human and animal diseases. Therefore, screening effective neutralizing antibodies for different pathogens is an urgent task. Among the methods for monoclonal antibody screening, B cell immortalization is an effective method to obtain neutralizing monoclonal antibody. Specifically, in this study, the bcl-6 and bcl-xl genes were connected by f2a and then the yielded product was ligated to a vector for retrovirus packaging. The swine lymphocytes immunized with PRRSV were infected the yielded mature viruses and cultured in the complete medium containing CD40L and IL21 cytokines. Then, CD21 was used as the marker to screen B cells with the magnetic bead method. Finally, monoclonal B cells were obtained and the secretion of antibodies was tested. The results showed that the plasmid, either being transfected alone or with the packaged plasmids, could be expressed, and that the packaged retrovirus could infect the cells. Moreover, the infected lymphocytes secreted antibodies, so did the screened B cells. Therefore, the method for screening monoclonal antibody against PRRSV was successfully established.
